Abstract: Objective To compare the clinical efficacy of covered and uncovered metal stents in treatment of malignant biliary obstruction. Methods 123 cases of malignant biliary obstruction from May 2003 to May 2014. The survival time, the stent patency rates, the effective and biochemical indexes between the two groups were analyze and compared, follow-up period ended in March 2015. Results The level of bilirubin, transaminase, alkaline phosphatase (ALP) was declined after the covered and uncovered metal stents placed by ERCP, and the results of the two groups had no statistical significance (P > 0.05). Also there was no significant difference of the incidence of postoperative cholangitis and the cumulative survival rate between the two groups (P > 0.05). One year survival rates was related to tumor types (r = -1.55, P < 0.05). Conclusions Covered and uncovered metal stents for malignant biliary obstruction have no statistically significant about remission of liver function, stent occusion and the cumulative survival rate.
